Some C code I wrote, maybe useful for switching instead of dumbass switch-case calling

clah.c

#include<stdio.h>

int map(int *arr, int (*(*foo)(int))(int), int choose) {
    printf("%d", foo(choose)(arr[0]));
}

int barfoo(int x) {
    return x - 1;
}
int foobar(int x) {
    return x + 1;
}

static int (*foo[])(int) = {foobar, barfoo};

int (*func(int x))(int) {
    return foo[x];
}

int main() {
    int a = 5;
    map(&a, func, 1);
    return 0;
}
